Abstract

We experimentally demonstrate plasmonic nanocircuits operating as subdiffraction directional couplers optically excited with high efficiency from free-space using optical Yagi-Uda style antennas at \textgreekl0 = 1550 nm. The optical Yagi-Uda style antennas are designed to feed channel plasmon waveguides with high efficiency (45% in coupling, 60% total emission), narrow angular directivity (<40°), and low insertion loss. SPP channel waveguides exhibit propagation lengths as large as 34 \textgreekmm with adiabatically tuned confinement and are integrated with ultracompact (5 $\times$ 10 \textgreekmm2), highly dispersive directional couplers, which enable 30 dB discrimination over \textgreekDl = 200 nm with only 0.3 dB device loss.
